I agree with Brett, I never seen a fragmentation on disks get above 5%
the machines running Solaris 1.x or 2.x.

The berkeley FFS, which is what UFS really is, is designed to
automatically defragment itself with use. You should not see any
significant fragmentation with normal usage patterns. You can check
the fragmentation by doing a "fsck -n" on the partitions. I have
rarely seen fragmentation on disks get above 5% on the machines I run.

THe fragmentation reported by fsck is probably not what you think,
and will probably never get gigh enough to consider defragging.
However, UFS filesystems DO get fragmented, and there's no tool
supplied with Solaris to defrag except to ufsdump/ufsrestore.
Fortunately, there IS a commercial tool to do it.
